Patent CA-2053146-C (CA)
Inventor: VULETIC BOGDAN
IPC: C02F5/00
Filed: 1991-10-10
Granted: 1997-03-11
Abstract: The invention relates to a process for the treatment of wash water from the gas washing system of an iron ore reduction plant, the wash water being brought into direct contact with the dust-laden gas in a gas washer, is removed from the latter and after solids separation is again supplied in cooled form to the gas washer. According to the invention this problem is solved in that wash water which is substantially freed from solids in a concentrator or thickener (1) is passed via a hot water tank (2) into a cooling tower (4) where the water is cooled and where there is simultaneously a separation of dissolved carbon dioxide, an enrichment with oxygen, a conversion of the calcium and magnesium hydrogen carbonates into carbonates and iron bicarbonate, as well as iron sul-phate into iron(III)-hydroxide and that said chemi-cally destabilized wash water is freed from the re--formed and residual solids in a further series-con-nected thickener (6) by adding flocculating and coa-gulating agents, is chemically stabilized and passed over a cold water tank (7).

Title: Hydraulic shock absorber
Inventor: BARRINGTON BURCHUS Q
IPC: E21B17/07
Filed: 1991-12-03
Granted: 1995-08-15
Abstract: A shock absorber apparatus for inclusion in a tool string which consists of outer and inner casings telescop-ically assembled with one casing having an uphole threaded joint member and the other casing having a downhole threaded joint member.  The concentric casings then define spaced, sealed voids communicating through a metering sleeve clearance that are filled with a compressible oil.  Shock wave induced relative movement of the casings from either direction causes a shock absorbing instantaneous displace-ment of oil from one void to the other via the metering clearance.  Alternatively, coil springs may be disposed in the voids to aid in shock absorption.

Title: System, method, and process for computer-controlled manufacture of three-dimensional objects from computer data
Inventor: PENN STEVEN M
IPC: B29C67/00
Filed: 1992-01-29
Granted: 2001-04-10
Abstract: A method and process for computer-controlled manufacture of three-dimensional objects involves dispensing a layer of liquid, insoluble material (25) onto a platform (15) at predetermined locations, which them hardens. A second media (35), preferably water soluble, is then sprayed onto this layer to thereby encapsulate the hardened insoluble media. The uppermost surface of this encapsulant is planed, thus removing a portion of the encapsulant to expose the underlying insoluble material for new pattern deposition. After the resulting planing residue is removed, another layer of liquid, insoluble media is dispensed onto the planed surface. The insoluble media can be of any color and may vary from layer to layer, and from location within a layer to location within a layer.  These steps are repeated. until the desired three-dimensional object (55), surrounded by a mold, is completed. At this point, the abject is either heated or immersed in a solvent, thereby dissolving the mold and leaving the three-dimensional object intact.

Abstract: The present invention relates to a counter--receptor, termed CD40CR, for the CD40 B-cell antigen, and to soluble ligands for this receptor, including fusion molecules comprising at least a portion of CD40 protein. It is based, at least in part, on the discovery that a soluble CD40/immunoglobulin fusion protein was able to inhibit helper T-cell mediated B- cell activation by binding to a novel 39 kD protein receptor on helper T-cell membranes. The present invention provides for a substantially purified CD40CR receptor; for soluble ligands of CD40CR, including antibodies as well as fusion molecules comprising at least a portion of CD40 protein; and for methods of controlling B-cell activation which may be especially useful in the treatment of allergy or autoimmune disease.

Abstract: An apparatus and method for supplying cab signal to a rail vehicle on a section of track composed of sequentially adjacent railway track circuit blocks. Respective receivers of each track circuit block are monitored for the presence of a vehicle within that block.  The cab signal apparatus is controlled to transmit a signal to a block when the output from the respective receiver in that block indicates a different condition from the adjacent receiver of an adjacent block.  Output voltages from adjacent receivers are compared to enable transmission of a cab signal. Comparison of adjacent receiver outputs is accomplished through use of a diode bridge.
